This post was created because of the email from one of my webhosting account… They said that my dedicated server is ready and I can now set up my own custom name server. They even offer to help if I don’t know how to do it. I just need to give them my account info…. sure… NOT.

Here’s how to do it in GoDaddy:

GoDaddy
1. Login to your GoDaddy Account.
2. Click on My Account
3. Click on Manage Domains
4. Click on the domain name you want to modify.
5. In the lower left corner of the page, there is a Host Summary. Click Add.
6. Enter the ns1 and ns2 and IP addresses. Then click OK.
7. Click the Nameservers icon across the top.
8. Change the nameservers to the ones you just created.

Try it! Goodluck!

I made this post because I myself found it hard to search the web looking for the device driver for our PK-336MB A4 webcam. Well, the good news is I found it.. and good news still, I’m going to tell you where it is as well as the other A4 webcam models:

PK-336MB
PK-635
PK-635M
PK-835
PK935
PK-7MAR
PK-636MA

Apache is the most well known open source web server there is! Open source?? Make that the most wildly used webserver on the internet, period!

It is believed (and i know they made a survey or study about it) that Apache takes 90% of all web servers in the internet. Most web hosting company, and I’ve once worked in one, use Apache.

This post will talk about how to setup Apache for Virtual Hosting

Setting Up A Virtual Host in Apache

create a completely seperate document root, cgi-bin directory, and logfile directory for each host. You can place these beneath the standard Debian prefix of /var/www or you may use a completely different root

root@irony:~# mkdir /home/www

root@irony:~# mkdir /home/www/www.example.com
root@irony:~# mkdir /home/www/www.example.com/htdocs
root@irony:~# mkdir /home/www/www.example.com/cgi-bin
root@irony:~# mkdir /home/www/www.example.com/logs

root@irony:~# mkdir /home/www/www.example.net
root@irony:~# mkdir /home/www/www.example.net/htdocs
root@irony:~# mkdir /home/www/www.example.net/logs
root@irony:~# mkdir /home/www/www.example.net/cgi-bin

root@irony:~# mkdir /home/www/www.example.org
root@irony:~# mkdir /home/www/www.example.org/htdocs
root@irony:~# mkdir /home/www/www.example.org/logs

root@irony:~# mkdir /home/www/www.example.org/cgi-bin

Here we’ve setup three different directory trees, one for each site. If you wanted to have identical content it might make sense to only create one, and then use symbolic links instead.

The next thing to do is to enable virtual hosts in your Apache configuration. The simplest way to do this is to create a file called /etc/apache2/conf.d/virtual.conf and include the following content in it:

#
#  We're running multiple virtual hosts.
#
Nameserver *

NameVirtualHost *

(When Apache starts up it reads the contents of all files included in /etc/apache2/conf.d, and files you create here won’t get trashed on package upgrades.)

Once we’ve done this we can create the individual host configuration files. The Apache2 setup you’ll find on Debian GNU/Linux includes two directories for locating your site configuration files:

/etc/apache2/sites-available

This contains configuration files for sites which are available but not necessarily enabled.
/etc/apache2/sites-enabled

This directory contains site files which are enabled.

As with the conf.d directory each configuration file in the sites-enabled directory is loaded when the server starts – whilst the files in sites-available are completely ignored.

You are expected to create your host configuration files in /etc/apache2/sites-available, then create a symbolic link to those files in the sites-enabled directory – this will cause them to be actually loaded/read.

Rather than actually messing around with symbolic links the Debian package includes two utility commands a2ensite and a2dissite which will do the necessary work for you as we will demonstrate shortly.

Lets start with a real example. Create /etc/apache2/sites-available/www.example.com with the following contents:

#
#  Example.com (/etc/apache2/sites-available/www.example.com)
#
<VirtualHost *>
ServerAdmin webmaster@example.com
ServerName  www.example.com
ServerAlias example.com

# Indexes + Directory Root.
DirectoryIndex index.html
DocumentRoot /home/www/www.example.com/htdocs/

# CGI Directory
ScriptAlias /cgi-bin/ /home/www/www.example.com/cgi-bin/
<Location /cgi-bin>
Options +ExecCGI
</Location>

# Logfiles
ErrorLog  /home/www/www.example.com/logs/error.log
CustomLog /home/www/www.example.com/logs/access.log combined

</VirtualHost>

ow we’ve got:

• Three directories which can be used to contain our content.
• Three directories which can be used to contain our logfiles.
• Three directories which can be used to contain our dynamic CGI scripts.
• Three configuration files which are being ignored by Apache.

To enable the sites simply run:

root@irony:~# a2ensite www.example.com
Site www.example.com installed; run /etc/init.d/apache2 reload to enable.

root@irony:~# a2ensite www.example.net
Site www.example.net installed; run /etc/init.d/apache2 reload to enable.

root@irony:~# a2ensite www.example.org
Site www.example.org installed; run /etc/init.d/apache2 reload to enable.

This will now create the symbolic links so that /etc/apache2/sites-enabled/www.example.org, etc, now exist and will be read.

Once we’ve finished our setup we can restart, or reload, the webserver as the output above instructed us to do with:

root@irony:~# /etc/init.d/apache2 reload
Reloading web server config...done.
root@irony:~#

atp-cache search ftp-server

This will suppose to to list all available ftp server . As you can see there are a few available server you can choose. Popular one is proftp.

To install the service do:

apt-get install proftp

This will start installing .. you know, displaying all those letters and words and stuff..

webserver:~# apt-get install proftpd

Run proftpd from inetd or standalone?

inetd
standalone

Initially selected standalone here.

And you’re done!

To start up the FTP service:

/etc/init.d/proftpd start

My original plan was to erase the whole thing and put Ubuntu on it. Tried it couple of days ago but didn’t work out.

After the boot up from the CD (requested a copy of Ubuntu 7.10) it displayed the little cross hair, then nothing…

I thought it’s probably the Vista… So I put in XP.. coz I tried installing Ubuntu over XP before, but the same thing happened!

So I wonder if this is a hardware issue on my laptop? It’s a NEO Empriva 540SVBe.

Will do a search later.

…

checking db.h usability… no
checking db.h presence… no
checking for db.h… no
configure: error: BDB/HDB: BerkeleyDB not available

At first, I thought this was just a case of $PATH not set up properly (since /usr/local) in not in the path by default). After setting up the path:

# echo $PATH
/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/BerkeleyDB.3.3:/usr/local/BerkeleyDB.3.3/bin:/usr/local/BerkeleyDB.3.3/include/
#

I still have the error.

I then added the path for the include files in the env

env CPPFLAGS=-I/usr/local/Berkeley/include

Did the configure and…

checking for db.h… yes

That fixed…

Next error…

So, before we could do the OpenLDAP compilation, we need to install first GCC and other prerequisite apps.

Here’s what I need to install on the box:

Need to install the following:

• gcc,
• ar (binutils)
• libiconv
• libintl
• Berkeley DB (db)

Donwload all packages on Sunfreeware and install.

change to the directory where the packages are located

# pkgadd -d <package name>

answer promp question (usually change of permission)

If all has been installed, we can proceed and compile OpenLDAP. Of course if that don’t work out, we could always installed it’s packaged version on Sunfreeware!

System Configuration: Sun Microsystems sun4u
Memory size: 1024 Megabytes

Sun-Blade-100 (UltraSPARC-IIe)

Prerequisites:

Depending on the requirements, there may be a need to install some third party softwares:

• OpenSSl
• Kerberos
• SASL
• Berkeley DB
• TCP Wrappers
• and others

Need to make sure the following variables is set:

(additional: Need to install gcc, ar (binutils) libiconv libintl-3.4.0-sol8-sparc-l as well as Berkeley DB on server)

With the initial installation I will set it up using

# ./configure

# make depend

# make

# make test

Finally,

# su root -c ‘make install’

That’s it, hopefully all will go well.. If it doesn’t, we’ll post the error (and hopefully solution).

Cheers!
